of Gaming Ballistic has started a Dungeon Grappling Kickstarter. He was a great player in my DnD 5e Majestic Wilderlands campaigns, and the author of several GURPS Supplements including Technical Grappling for GURPS.
The basic idea is that there a better way of dealing with grappling. Doug developed a set of mechanics that takes the same basic mechanics of rolling to hit and inflicting damage and turns the result into something meaningful when it comes to grappling. He did this for GURPS and now he doing this for classic DnD, Pathfinder, and DnD 5e with the kickstarter.
Doug's project already funded however further support will allow him to pay for a ebook layout and full color art. I hope you will support him.
